An ad- 1 tdrawings; ditional lever 1g is secured on the shaft 14 and Fig. 1 is avertical cross section through part engages a r0d'19 h h is acted upo bya comr the apparatus; Fig; 2' is a side view of the press sp s n sed ina housing 20. thus apparatus; Fig. 3 shows details of the feed gear p nt yh dl s h 1 0! the nnecting rod 16 against the cam 15 and serving tolower the rollers 11 at the proper time.

The piece discharged between the discs 10 and its counter-rollers 11, asa result of the velocity imparted to it, first hits the stationary stops21 and then falls down flat upon the assembling plate 22 or upon thepiece previously received. The assembling plate22 also has stationarystops 23, while oscillating or floating stops 24 and 25 are mounted onshafts 26, 27 and are adapted to ensure uniform stacking of the pieces.The stops 24 receive their movement from a cam 28 on the shaft 4, bymeans of a roller on a lever 29 which is secured on the shaft 26carrying the stops 24. The shaft 26 also carries an additional lever 30which is acted on by a tension spring 30' by which the roller of thelever 29 is kept in contact with the cam 28. The movement of the stops24 is indicated by dotted lines in Fig. 1. The stops 25 carried on theshaft 27 are moved by means of the shaft 26 through a roller on a lever31 carried on the shaft 26 and which roller engages a fork-shaped lever32 secured on the shaft 27 so that the movement of the shaft 26 istransmitted to the shaft 27.

For counting the pieces received from the machine and reaching thedistributing plate 22, the following means are provided.

On the shaft 4, which, as already mentioned, runs in proper timedrelation to the machine, an additional cam 33 is secured and by means ofthis cam a double armed lever 35 is caused to swing freely upon a shaft34. One arm 36 of this lever carries a roller 36' engaging the cam 33and the other arm 37 carries a pawl 38, while a tension spring 44 actingon the arm 37 keeps the roller 36 in contact with the cam 33. By meansof the pawl 38 a toothed gear wheel 39 is turned to the extent of onetooth each time, the cam 33 being so arranged-that the movement of thelever 35 takes place within the period during which a piece wouldnormally be located between the discs 10 and their counter-rollers 11.In order to ensure that gear wheel 39 is moved by one tooth only withthe actual discharge of a piece from the discs 10 and theircounter-rollers 11, a feeler 41 is carried by a rocking shaft 40, and isbalanced by a counter-weight 42, so that it swings upwardly above theperiphery of the discs 10, so long as there is no newspaper or otherpiece between the discs 10 and their counter-rollers 11. In the upperposition of the feeler 41, a tail piece 43 secured to said shaft 40projects into the path of a swinging arm 38 connected with the pawl 38so that during the next movement of the angle lever 35, the pawl 38 isdisengaged from the feed gear wheel 39, and the pawl 38 is thusprevented from imparting feed movement to the wheel 39. If, on the otherhand, a piece is passing between the discs 10 and their counter-rollers11, the feeler' 41 is depressed by the piece itself, so that the tailpiece 43 swings out into the dotted line position,

and the arm 38' of the pawl 38 is not engaged by the tail piece 43, andthe pawl 38 therefore engages with the teeth of the feed gear wheel 39,so that the latter is turned by one tooth. A counter-pawl 38" insuresthe proper positioning of the feed gear wheel 39 after each feedmovement. From the foregoing it will be" understood that each feedmovement of the wheel 39 corresponds to the delivery of a sheet or otherpiece to the 95+ sembling plate 22.

When a predetermined number of pieces have been accumulated each time onthe assembling plate 22, this accumulation is removed as a whole fromthe said plate. For this purpose the assembly plate 22 with thestationary stops 23 secured thereon is adapted to shift horizontally ina direction perpendicular to the direction of movement of the piecesbetween the discs 10 and rollers l1. Brackets 45 on the plate 22 aremounted on a cross-bar 46 which is carried between slide pieces 47adapted to move in slide guides 48. In Fig. 2 the right hand position ofthe plate 22 is shown by dotted lines. This displacement of the plate 22is effected by a lever pair 49 having forked ends embracing thecross-bar '46, which latter are attached to a rocking shaft 50, operatedin the following manner. The shaft 5 operated in proper timed relationto the apparatus carries a crank 51 which-by means of a connecting rod52continuously imparts swing movement to a lever 54 loose on the rockingshaft 50. On the said shaft 50 is secured a segment 56 which has a notchor gap on its circumference. When a pawl 53carried by the lever54-engages the said notch, the segment 56 and the axle 50 receive thepartial right-hand turn necessary for the displacement of the plate 22,while the return of the distributing plate 22 into the piecereceivingposition is effected by an extension 57 which is provided on the pawl 53and extends over the segment 56.

For timing the displacement of the distributing plate 22 so that it iseffected only after a definite number of pieces have accumulatedthereon, the following means are provided.

A cam or rim 58 is provided on the feed gear wheel 39 and has the formof an annular ledge projecting laterally from the said wheel. In this 59can be closed by insert-pieces 60 fastened therein by means of screws61, so as to divide the teeth of the wheel 39 into groups each having anumber of teeth corresponding to the number of sheets to be accumulatedon the plate 22. If for example-15 pieces are to be accumulated eachtime on the distributing plate 22 and removed from. it together, fourindentations 59 must be left open thus subdividing the feed gear wheel39 into four times fifteen teeth. On the surface of the cam 58 runs aroller 64 which is mounted on the lever 63 which is fixed on a shaft 62and is affected by a spring 65 which is connected to a lever 66 alsofixed on the shaft 62 so that the roller 64 is kept in engagement withthe cam. When fifteen teeth of the wheel 39 have been fed each time, theroller 64 enters one of the indentations 59, and the lever 66 thenassumes the position shown in the drawings in dotted lines. This lever66 is connected by a tie rod 67 with a segment 68 loosely mounted on theaxle 50, which segment is thus swung into the dotted line position. Thesegment 68 is arranged close alongside of the said feed segment 56carrying the notch 55 these segments 56 and 68 have the same radius. Thepawl 53 is of such a width that it bears on the circumference ofboth'segments and the arrangement is such that the segment 68 laterallycovers up the notch 55 of the feed segment 58 in the full line positionFig. 2, while it exposes this notch whenturned into the dotted lineposition. So long as the roller 64 of the lever 63,

bears on the raised surface of the cam 58 therefore, the permanentlyswinging pawl 53 cannot d enter the notch 55 of the feed segment 56; athis engagement is possible only when the roller 64 has entered one ofthe indentations 59 and the segment 68 has been swung out into thedotted line position. This position is retained during one revolution ofthe shaft 5 and during this period the pawl 53 swings the feed segment56 and thereby displaces theassembling plate 22 for removing the sheetsaccumulated thereon and also efl'ects the return of the assembling plate22 into the sheet or piece receiving position. At the beginning -ofthenext revolution and assuming that the next piece is being properlyconveyed to the assembling plate 22, the roller 64 leaves theindentation 59 and the segment 68 has returned to the position shown sothat the pawl 53 during its continued oscillations again slides withouteffect over the circumference of the segment 68 until the roller 64enters the next indentation of the cam 58.

The accumulated pieces moved in the above mannerare received in thefirst place by a drum 69 which has a rubber cover on its circumferenceand by the roller 70 likewise provided witha rubber cover. The drum 69runs loosely on the shaft 5 and turns in the opposite direction to saidshaft. This drum 69 is driven by a gear 71, solidly connected with itthrough the medium of intermediate wheels '72 and 73 from the gear 74secured on the shaft 5. The roller 70 is driven by means of a gear 75 onits shaft, through the medium of an intermediate wheel 76 from the saidgear 71 connected with the drum 69.

The drum 69 and the roller 70 convey on to a table 76 the accumulated,pieces received by them from the plate 22. The table 76 is attached to9. depending stem 78 vertically displaceable in a frame 77 and isadapted to add these accumulated sheets s (Fig. 4) to the main stack Swhich latter rests on two supporting plates 79 and 79 which can be swunginwardly and outwardly. Each tkme that a group of pieces s is fed to itthe table 7 must execute vertical up-and-down movements in proper timedrelation to the operation of the other parts of the apparatus and thesemovements are efi'ected in the following manner.

The said shaft 50 has secured thereon a lever 80 carrying a pin 81 atits free end. Beneath the shaft 50 there is mounted a rocking shaft82from which a lever 83 extends upwardly. This lever 83 carries a smalldouble-arm pawl lever 85 adapted to rotate on a bolt 84andbearing,underthe action I of a torsion spring 86, with its lower armagainst a stop pin 87 on the lever 83, while the end of its upper armprojects into the path of the pin 81 on the lever 80'. On the shaft 82is attached a second lever 88 which is connected to a tension spring 89which pulls it against a stop pine 90.

When the assemblingplate 22, after having delivered a group of pieces tothe drum 69 and roller 70, moves back again into the piece receivingposition and t'ie lever 80 passes from the dotted-line into the vull-line position, the pin 81 engages the upper end of the lever 85 andswings the lever 83 towards the right (Fig. 2) until the said pindisengages said lever, whereupon the spring 89 again brings the lowerlever 88 into engagement with the pin 90. This swinging of the lever 88is transmitted, through a tie rod 91 to a tripper 92v of aone-revolution coupling 93 of any suitable or well known type, thuscausing the shaft 94, after its release, to execute one revolution andto then come to rest again. The shaft 94 is driven in this connectionthrough the medium of the gear 93' on the one revolution coupling and ofthe intermediate wheels 95- and 96, by the gear 97 on the shaft 5; theexample drawn being in the ratio of 1 to 8, so that eight revolutions ofthe machine cause one revolution of the shaft 94. A toothed segment' 101is mounted to turn about and swinging movement is imparted thereto by acrank 98 on the shaft 94, through the medium of a connecting rod 99connected with it. This segment 101 is in mesh with a gear 103 on ashaft 102, which in the drawings (Fig. 2 coincides with a' second gearon the same shaft. The latter engages the stem 78 of the table 76 whichstem is made as a round rack throughout a part of its length, so thatthe swinging movement of the tooth segment 101 causes the stem 78 andthe table 76 borne by it to move upwardly and downwardly.

The adding of the accumulated pieces s to the main stack S during theupward movement of the table 76 is efiected in the following manner.

. The main stack is carried by the said supporting plates '79 and 79'which'are attached to arms 104 and 104' reaching under the longitudinaledges of the pieces. The arms 104 and 104 are mounted to swing on shafts105 and 105 in the frame 77. When the table 76 is raised so far that thepiece lying uppermost on top of it has arrived in a position close underthe supporting plates 79 and 79, the arms 104 and 104 carrying thelatter are automatically swung out, so that the "main stack S is placedon top of the pieces s carried by the table 76; and during the furtherupward movement of the table, the main stack S then participates in thismovement together with the newly 'added pieces s. After the table hasreached its highest position, the arms 104 and 104' with the supportingplates 79 and 79 again swing in under what is now the main stack,

whereupon the table 76 again moves downward.

The supporting plates 79 and 79' carry recesses 106 (Fig. 2) whichproject from their free longitudinal edge as far as the first bendvisible in the drawings, and the parts remaining between these recessesreach, when the arms again swing inwardly, into corresponding recessesprovided in the table 76, so that the supporting plates 79 and 79' canswing in unhindered in the highest position of the table 76.

For the swinging of the arms 104 and 104', which must always take placeduring the upward movement of the table 76, two shafts 107 and 168 aremounted on the frame 77. The shaft 107 is driven, through the medium ofa sprocket wheel 109, a chain 111 and a sprocket on the shaft 94, fromthis shaft 94. A bevel gear 112 on the 'shaft 107 drives a bevel gear112 of equal sizeon the shaft 108 which moreover carries an adjustablecam 113. The ratio is so chosen that one revolution of the shaft 94results in one revolution of the shaft 108. On the shaft 105' of the arm104' is secured an angle lever 114 which on one of its two arms carriesa roller 115 which is held against the surface of the cam 113 by atension spring 116 connected to the other arm or said lever. On theshaft 105 of the arm 104,-is seemed an angle lever 117 one of whose arms5 has a slot at its freeend for engagement by an extension of a bolt118, by means of which the said roller 115 is carried on the lever 114.I The other arm-of this angle lever 117 is connected to a. tensionspring lllf. The roller 115'therefore acts on both arms 104 and 104which are swung inwardly with the supporting plates 79 and 79' beneaththe main stack, as long as the roller bears on the low portion of thecam 113, so that the inward swinging of the arms-where no resistance ofany kind has to be overcome-is effected under the action of the twotension springs 116, while the outward swinging is positively effectedby the action of the cam 113 when the roller 115 passes from the low tothe high portion of said cam where it is necessary to overcome thepressure of the main stack resting upon the plates 79, 79.

The inward swinging of the arms 104 and 104' always takes place when thetable 76 is at the highest position, while the outward swinging, on theother hand, is variable and is governed by the height of the group ofpieces s resting on the table 76 at any one time. This must take place,with any height of the pieces s whenever its uppermost piece, during theupward movement of the table, has reached a point close under thesupporting plates 79 and 79. For that reason the cam 113 is made in twoparts, of-which the part 113 controlling the passage from the high tothe low portion and therefore effecting, together with the tensionsprings 116, the inward swinging of the arms 104 and 104', is solidly orpermanently secured to the shaft while the other part 113" whichcontrols the passage from the low to the high portion, for the outwardswinging of the arms 104 and 104, is free to turn on the shaft 108, oron the hub of the, part 113' and can be secured by a screw 119 to suitthe height of the group of sheets s being handled at any one time.

Means are also provided whereby each group of sheets 3 added to thestack may be turned to a position opposite to that of the precedinggroup 8. This is advantageous with folded newspapers and the like, ifonly for the reason that these are thicker at the side having the crossfolds than at their other sides. The arrangement according to thisinvention is such that each time a group of sheets s is to be added tothe main stack the group s is received upon the table 76, and eachalternate group is turned through 180 degrees in the plane of the sheetsso that the cross folds in the groups alternately lie on opposite sidesof the main stack S. To effect this turning movement the stem 78 securedto the table 76 extends through a sleeve 120 mounted on the frame 77 andhaving a helical cam surface 122 extending through 180 degrees andadapted to engage a pin or roller 123 projecting from the side of thestem 78, the cam surface 122 being formed so as to cause the stem 78 toturn through 180 degrees during its upward movement, but to allow ashort vertical movement-without rotationat the beginning and at the endof the upward movement of the stem.- The pin or roller 123 traverses thecam surface 122 and effects the turning of the stem 78 when the sleeve120 is in the proper position. In the position shown in Fig. 2, the nextupward movement of the stem 78 would take place with a simultaneousturning through 180 degrees, since the pin 123 on the stem 78 bears onthe lower end of the cam 122. A suitable gap is formed in the sleeve 120so that the stem 78 is not rotated during its subsequent downwardmovement. After the next upward movement of the table 76 the sleeve 120is turned through 180 degrees, in the same direction as that ,of thetable, the said sleeve 120 being turned through 180 degrees after everysecond upward movement of the table 76 by means of the followingmechanism. The shaft 94 makes one revolution for each upward anddownward movement of the table 76 and has a gear 124 in mesh with a gear125 of equal size on the shaft 126. The gear 124 has teeth only on sucha part of its circumference that its full revolution only results inexactly one half revolution of the gear 125 and of the shaft 126, whichlatter carries the roller wheel 127 of a Maltese gear, and one fullrevolution of the wheel 127 imparts to the Maltese cross 129 on theshaft 128 movement through 90 degrees. On the shaft 128 of the Maltesecross 129 there is provided a gear 130 and this is twice as large as agear 132 which meshes therewith and is secured on a shaft 131. Onequarter of a turn of the Maltese cross 129 therefore results, each time,in half a revolution of the shaft 131, whichlatter carries a spiral gear133 which drives a similar gear 121 secured on the said sleeve 120.

Considering the above mechanism in the position shown at Fig. 2 it willbe understood that during the next complete revolution of the shaft 94the table 76 is caused to rise with a simultaneous turn through degrees,the shaft 126 and the roller wheel 127 turn through half a revolution ina clockwise direction, during which the roller 12,7 reaches thediametrically opposite position shown by dotted lines without impartingmovement to the Maltese cross 129. After the completion of therevolution of the shaft 94, the

pin 123 of the stem 78, is located at the right hand side, since thetable 76 during its upward movement has turned through 180 degrees. Thepin 123 therefore no longer bears on the lower extremity of the camsurface 122, so that during the next revolution of the shaft 94 thevertical movement of the table 76 takes place without a simultaneousturning movement, but the roller 127' of the roller wheel 127 moves fromthe dotted into the full-line position so that during the second half ofits half revolution the roller 127 turns the Maltese cross 129 throughninety degrees, so that the sleeve 120 is turned through 180 degrees inthe same direction as the table was previously turned, so that the pin123 of the stem 78 again engages the lower extremity of the cam surface122. Since only half the revolution of the roller wheel 127, (on accountof the partial toothing of the gear 124) only takes place during thedescent of the table 76 and the movement of the Maltese cross 129moreover only takes place in the second 1' half of the half revolutionof the roller wheel 127, the turning of the sleeve 120 commences onlyafter the table 76 has made one half of its downward movement; thesleeve can therefore be turned through 180 degrees without hindrance.

With reference to the action of the said lever 80 on the shaft 50 of themeans for releasing the one-revolution coupling 93 by swinging the lever88, it should be understood that movement of the lever 88 is effectedonly when the assembling plate 22 moves back into the sheet-receivingposition, that is to say, when the lever 80 passes from the dotted tothe full-line position, Fig. 2, since with the opposite movement of thelever 80 its pin 81 merely swings the small pawl lever 85, which turnsit on its bolt 84. Before the lever 80 has reached the dotted lineposition, however, the pawl 85 again slides off the pin 81 and thetorsion spring 86 brings it again into contact with its stop-pin 87.
